    It sounds like your after the extern keyword. Do a board search, 'cos I know there's been talk of this recently.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    The quote isn't quite right, I couldn't fit all the words in! The real one is:

    >movie
    The movie is quite old, and is somewhat slow. It's an acquired taste, imho. But I like it!

    >book
    This is better, it explains a lot more than the film ever could. Worth a read I think.

    Yes
    The best way is to put the structure in an include (.h) file, then include that in all the .c files which need it.
